Improvement in kerosene-lamp burners



UNITED STATES PATENT }OFFICE.Q

HENRY,F. ADAMS AND WILLI .A.M BERRY, on SYRACUSE, new YORK,

"Specification forming part of Letters Patent No. 35,660, dated June 24, 1862.

To all whom it may concern:

Be it known that-we, HENRY F. ADAMS and WILLIAM BERRY, of the city of-Syracuse,

county of. Onondaga, and State of New York, have invented certain new and useful Improve.- ,ments in Lamp-Heads; and we do hereby declare and ascertain the same, reference being had to the accompanying drawings, in which x1 igure 1 is an external view of our lamphead attached to an Ordinary lamp. Fig. 2 is a perspective View of thelamp-head and wick:

* fork with the cap 0 removed. Fig. 3 is a top view of the lamp-head with cap removed.

Fig. 4 is a bottom view of the lamp head with the ordinary screw lam ptop, '1, secured in its. means of radial arms. This screw lamp-top and the cap Care of ordinary construction. A

The object of our invention is to supply, in

, a peculiar manner, a sufficient quantity of air and draft, and in such peculiarly-arranged currents to the flame of ordinary kerosene and other carbonaceous oil lamps as to cause them to burn brightly and free from smoke, and

with a wide and steady flame, without the necessity ofusingglasschimneys or tubes, which "are very inconvenient and liable to be broken in use or cracked by:the effect of the heat.

Our invention consists of a wick-tube (made somewhat larger than those heretofore used) which is surrounded by a conical-shaped airchamber, A, made at its lower end considerably larger thanthe screwtop T, and secured to it by radial arn s, so as to leave openings through which air can pass freely up the airchamber through said openings. Around the bottom of this air-chamber we form a large concave flange, F, which serves to gather the air and concentrate it through the bottom openings into the air-chamber, which, growing smaller at the top, continues to increase the rapidity of the volume of ascending air bined operate to support and spread the flame and supply it with abundance of air or oxygen to support perfect combustion and produce a steady, broad, and clear flame, and while it is thus rendered portable and convenient in every respect, it is also smoke-consuming and free from any offensive odor.

Any convenient device may be adopted for raising and lowering the wick, one very cheap form.of which consists of a small fork, as sometimes nsed in camphene-Iamps, or the ordinary ratchet wick-elevator in common use on kerosene-lamps maybe used in our improved lamp head for that purpose.

Having thus fully described our invention, what we claim as new, and desire to secure therein by Letters Patent, is

The combination of the large concave flange F and conical air-chamber A, (havingbottom openings, as described,) with the small concave flange It, (inolosed within the cap 0,) and said flange R being constructed with peculiarly formed center and outside openings, as specified, and the whole being combined and arranged specifically as described, and for the purposes set forth.
